EXSLT - str:split

The str:split function splits up a string and returns a node set of token elements, each containing one token from the string.

The first argument is the string to be split. The second argument is a pattern string. The string given by the first argument is split at any occurrence of this pattern. For example:

str:split('a, simple, list', ', ')      
      

Gives the node set consisting of:

<token>a</token>
<token>simple</token>
<token>list</token>

If the second argument is omitted, the default is the string ' ' (i.e. a space). Thus:

str:split('date math str')      
      

Gives the node set consisting of:

<token>date</token>
<token>math</token>
<token>str</token>

If the second argument is an empty string, the function returns a set of token elements, each of which holds a single character. Thus:

str:split('foo', '')          
        

Gives the node set consisting of:

<token>f</token>
<token>o</token>
<token>o</token>

The template version of this function returns a result tree fragment consisting of a number of token elements.
